  By the way, in many public facilities, particularly hospitals and nursing care facilities, handrails for assisting walking are installed in corridors, stairs, and indoors. These handrails have gripping bars that are actively gripped by the user, and regular sterilization of the gripping bars is indispensable.

  The disinfection devices described in Patent Literatures 1 and 2 are configured to disinfect the floor surface, and cannot be applied to disinfection of handrails. In addition, in Patent Literature 2, ultraviolet rays are emitted from the lower surface and side surfaces of the traveling machine for the purpose of expanding the sterilization range. However, ultraviolet rays, particularly UV-C, are harmful to the human body, and from the side surface. Is not preferred.

  Due to such circumstances, handrail disinfection is generally carried out by washing the gripping rod using the above-described disinfectant, which has a limited disinfection effect and is effective for disinfection of long handrails. There is a problem that a lot of trouble is required. In recent years, a hand-held ultraviolet irradiation device has been put to practical use, and this device can be used for disinfecting the gripping rod. However, in this case, human labor is required and protection including harmful ultraviolet light is included. There is a problem that the labor burden of the worker who was used is large.

  An object of the present disclosure is to provide a disinfecting device that can effectively remove bacteria from a handrail gripping bar without requiring any manual operation, and a handrail equipped with the disinfecting device. .

  The disinfection device according to the present disclosure grasps a gripping bar of a handrail, and a mobile body that moves in the longitudinal direction of the gripping bar, and is held by the mobile body and irradiates a surface of the gripping bar with ultraviolet light. An ultraviolet irradiator.

  According to the present disclosure, the moving body grips the handrail gripping rod and moves in the length direction, and during this movement, the ultraviolet irradiator held by the moving body operates to cause the surface of the gripping rod to emit ultraviolet light. Is irradiated. Therefore, pathogens and viruses adhering to the surface of the gripping rod can be killed by the action of ultraviolet rays, and the handrail gripping rod can be effectively disinfected without requiring any human intervention.

  Further, the mobile body includes at least one drive wheel that is in rolling contact with the peripheral surface of the gripping rod and a plurality of driven wheels that are in elastic contact with the peripheral surface of the gripping rod at a different circumferential position from the driving wheel.

  The mobile body stably grips the gripping rod by the driving wheel that rolls on the peripheral surface of the gripping rod and the plurality of driven wheels that elastically contact the peripheral surface of the gripping rod at a circumferential position different from the driving wheel. Then, it is moved by the rotation of the drive wheel in this state. The driven wheels can be elastically contacted, for example, by applying a biasing force toward the peripheral surface of the gripping rod by springs interposed at the respective support positions.

  The moving body is a first body that includes at least one drive wheel that rolls on the peripheral surface of the gripping rod and a plurality of driven wheels that elastically contact the peripheral surface of the gripping rod at a different circumferential position from the drive wheel. And a plurality of driven wheels that are spaced apart from the first body in the longitudinal direction of the gripping bar and elastically contact the circumferential surface of the gripping bar at a plurality of locations in the circumferential direction, and hold the ultraviolet irradiator. It comprises two bodies and a bellows-like connecting body connecting the first body and the second body.

  The first body holds the gripping rod with the driving wheel and the plurality of driven wheels, and the second body holds the gripping rod with the plurality of driven wheels at a position away from the first body. The first body and the second body are connected by a connecting body. The first body moves by the rotation of the drive wheels, and the second body follows the first body. The mobile body can hold a gripping bar at two locations separated in the length direction and can move in a stable posture. The connecting body has a bellows shape, and maintains a connected state by being deformed at the bent portion of the gripping rod, thereby enabling movement at the bent portion.

  Further, a light-shielding member is provided which surrounds the outside of the mobile body including at least a peripheral portion of the ultraviolet irradiator.

  The light-shielding member surrounds the peripheral portion of the ultraviolet irradiator and shields ultraviolet light, thereby preventing ultraviolet light harmful to the human body from leaking to the outside.

And a control unit for stopping the operation.

  The control unit operates based on the remaining charge amount of the rechargeable battery. For example, when the remaining charge amount is low, the control unit moves the mobile unit to a predetermined position, and stops the movement of the mobile unit and the operation of the ultraviolet irradiator. The predetermined position is, for example, a position of a charging station provided in the middle of the moving route, or a position where collection by the user is easy. In the former case, the shortage of the remaining charge amount can be solved by contact or non-contact charging with the charging station, and in the latter case, the shortage of the remaining charge can be solved by the charging by the collector, and the driving can be continued.

  The vehicle further includes an obstacle sensor that detects an obstacle ahead of the moving route, and a control unit that operates based on a detection result of the obstacle sensor and stops the mobile machine.

  The control unit operates based on the detection result of the obstacle sensor. For example, when a user gripping the gripping bar is detected in front of the moving path, the control unit stops moving the mobile body to avoid a collision. In this case, it is desirable to stop the operation of the ultraviolet irradiator in order to avoid the influence on the user. In addition, by providing a stopper at the end of the moving path, the mobile machine can be automatically stopped according to detection of the stopper by the obstacle sensor.

  Further, a transmission unit for transmitting peripheral information of the mobile device to an external device is further provided.

(Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram illustrating a usage state of the sterilization apparatus according to the first embodiment. In the figure, reference numeral 1 denotes a handrail to be disinfected, which is constituted by fixing and supporting a gripping rod 10 to be gripped by a user to a side wall of a corridor, a staircase, or the like by brackets 11, 11 at a plurality of locations in a longitudinal direction. ing.

  The sterilization apparatus includes a moving body 2 that is set so as to straddle the gripping rod 10 from above and moves in the length direction of the gripping rod 10. The illustrated mobile body 2 is configured by connecting a first body 3 and a second body 4 with a connecting body 5. 2 is a cross-sectional view taken along the line II-II of FIG. 1 schematically illustrating the internal configuration of the first body, and FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 1 schematically illustrating the internal configuration of the second body. is there.

  The first body 3 shown in FIG. 2 is intended for a gripping bar 10 having a circular cross section, and has a thin cylindrical housing 30 with a part of the circumferential direction being missing, and one drive supported inside the housing 30. A wheel 31 and two driven wheels 32 are provided.

  The drive wheel 31 is supported at the center of the inner surface of the housing 30 in the circumferential direction so as to be rotatable around an axis orthogonal to the length direction and the radial direction of the housing 30. The drive wheel 31 is connected to a moving motor 33 fixed to one side of the support position, and is driven to rotate by the moving motor 33.

  The two driven wheels 32 are supported at both ends in the circumferential direction of the inner surface of the housing 30 so as to be rotatable around an axis orthogonal to the length direction and the radial direction of the housing 30. These driven wheels 32 are urged radially inward by urging springs 34 interposed between the respective support shafts and the inner surface of the housing 30.

  As shown in FIG. 2, the first body 3 as described above is set by rolling the drive wheel 31 and the two driven wheels 32 on the peripheral surface of the gripping rod 10. The two driven wheels 32 are in elastic contact with the peripheral surface of the gripping rod 10 by the urging force of the urging spring 34 and are pressed against the peripheral surface. Further, the elastic contact positions of the two driven wheels 32 are separated from each other by 90 ° or more on both sides of the rolling contact position of the drive wheel 31, and the urging force of the urging spring 34 causes the drive wheel 31 to It also acts as a push. Therefore, the gripping rod 10 is gripped by the driving wheel 31 rolling on the peripheral surface and the two driven wheels 32 elastically contacting the peripheral surface, and the first body 3 is rotated by the driving of the driving motor 31 by the movement motor 33. In response, it moves as shown by the white arrow in FIG.

  It is desirable that the peripheral surfaces of the driving wheel 31 and the driven wheel 32 be subjected to a non-slip treatment, for example, by applying a non-slip material such as rubber. It is desirable to have a concave curved surface corresponding to the peripheral surface of No. 10. Thus, the gripping bar 10 can be more firmly gripped, and the rotation of the drive wheel 31 can be surely performed. The housing 30 is made of an elastic material, and the elastic restoring force of the housing 30 is applied to the urging force of the urging spring 34, so that the gripping bar 10 can be gripped more reliably.

  The two driven wheels 32 can be displaced in the radial direction of the housing 30 against the urging of the urging spring 34, and follow the slight change in the shape of the gripping bar 10 to maintain the elastic contact state. Accordingly, the first body 3 can move, for example, over the mounting portion of the bracket 11 shown in FIG. The missing portion of the housing 30 is necessary to allow passage of a support leg (indicated by a two-dot chain line in FIG. 2) that supports the bracket 11 on the side wall 12.

  Further, inside the housing 30, a moving motor 33 and a rechargeable battery 6 serving as a power source for irradiating ultraviolet rays to be described later, and a control unit 7 for performing a control operation to be described later are provided with a driving wheel 31 and two driven wheels 32. Installed to avoid interference.

  Further, an obstacle sensor 35 is attached to the outside of the first body 3 as shown in FIG. The obstacle sensor 35 is, for example, an optical sensor including a light emitting unit that emits light forward in the traveling direction as indicated by an arrow, and a light receiving unit that receives light reflected from the obstacle. It detects the presence or absence of an obstacle on the traveling route, such as a user's finger or the like gripping the object.

  On the other hand, the second body 4 shown in FIG. 3 includes a housing 40 having a thin-walled cylindrical shape with a part in the circumferential direction being omitted, similar to the housing 30 of the first body 3. Two driven wheels 41 and four ultraviolet irradiators 42 are attached.

  The three driven wheels 41 are supported at both ends and a central portion of the inner surface of the housing 40 in the circumferential direction so as to be rotatable around an axis orthogonal to the length direction and the radial direction of the housing 40, respectively. These driven wheels 41 are urged radially inward by urging springs 43 interposed between the respective support shafts and the inner surface of the housing 40.

  The ultraviolet irradiator 42 is a light emitting element or an ultraviolet lamp that emits ultraviolet light, particularly, ultraviolet light (UV-C) having a short wavelength of 280 nm or less and having an excellent sterilization effect. In FIG. 3, two ultraviolet irradiators 42 are fixed to the inner surface of the housing 40 at appropriate intervals in the circumferential direction between the support positions of the three driven wheels 41, respectively. Is irradiated.

  The second body 4 as described above is set by rolling three driven wheels 41 on the peripheral surface of the gripping rod 10 as shown in FIG. The driven wheel 41 elastically contacts the peripheral surface of the gripping rod 10 by the urging force of the urging spring 43, and the respective elastic contact positions are separated from each other by 90 ° or more. Therefore, the gripping rod 10 is gripped by the three driven wheels 41 which are in elastic contact with the peripheral surface. The second body 4 is connected to the first body 3 by the connecting body 5, is pulled by the first body 3 that moves as described above, and moves along the gripping rod 10 with the rolling of the driven wheel 41. be able to.

  The three driven wheels 41 can be displaced in the radial direction of the housing 40 against the urging of the urging spring 43, and follow the shape change of the gripping rod 10 to maintain the elastic contact state. The fuselage 4 can move over a shape change portion such as a mounting portion of the bracket 11 similarly to the first fuselage 3. The missing portion of the housing 40 is provided to allow the support leg of the bracket 11 to pass through, like the missing portion of the housing 30 of the first body 3.

  The first body 3 and the second body 4 are separated from each other in the length direction of the grip bar 10, and the mobile body 2 is in a stable posture by gripping the grip bar 10 at two locations separated in the length direction. Can be moved. The connecting body 5 that connects the first body 3 and the second body 4 has a bellows shape as shown in FIG. 1 and can be bent and deformed in a direction orthogonal to the moving direction. Therefore, the mobile body 2 including the first body 3 and the second body 4 can move with the deformation of the connecting body 5 even at the bent portion of the gripping rod 10. FIG. 4 is an explanatory diagram of a moving state of the handrail at the bent portion, and for example, shows a moving state of the mobile body 2 at the bent portion of the gripping bar 10 at the transition from the corridor to the stairs.

  The four ultraviolet irradiators 42 fixed to the inner surface of the housing 40 face the gripping rod 10 gripped by the three driven wheels 41, and the ultraviolet light emitted by each of the ultraviolet irradiators 42 is shown in FIG. It spreads as shown by the two-dot chain line, and is irradiated on the entire upper surface and both side surfaces of the gripping bar 10. The surface of the gripping bar 10 is effectively sterilized by ultraviolet irradiation inside the moving second body 4 over substantially the entire length of the moving range of the moving body 2.

  The housing 40 surrounds a peripheral portion of the ultraviolet irradiator 42 from the outside, and also functions as a light shielding member that shields the ultraviolet light radiated to the holding rod 10. This can prevent ultraviolet rays harmful to the human body from leaking to the outside. Leakage of ultraviolet rays can be more reliably prevented by providing a separate light blocking member that covers the entire mobile unit 2.

  In FIG. 3, three driven wheels 41 and four ultraviolet irradiators 42 are shown side by side on the same cross section, but the ultraviolet irradiators 42 are preferably arranged side by side on a different cross section from the driven wheels 41. desirable. Thereby, it is possible to eliminate the overlap between the ultraviolet irradiation position and the rolling contact position of the driven wheel 41, and to satisfactorily perform the ultraviolet irradiation on the surface of the gripping rod 10.

  A rechargeable battery serving as a power source for the ultraviolet irradiator 42 and the above-described moving motor 33 may be provided inside the housing 40, and when used together with the rechargeable battery 6 provided in the housing 30 of the first body 3, The operation time accompanying the movement and the irradiation of ultraviolet rays can be lengthened.

  Further, an imaging unit 44 is attached to the outside of the second body 3 as shown in FIGS. The imaging unit 44 is, for example, a camera having an imaging area on the opposite side of the side wall 12 to which the handrail 1 is fixed, as indicated by an arrow in FIG. Is taken.

  FIG. 5 is a block diagram showing a configuration of a control system of the sterilization apparatus. The control unit 7 provided inside the first body 3 includes a CPU 70, a ROM 71, and a RAM 72, and controls the movement motor 33 and the ultraviolet irradiator 42 by the operation of the CPU 70 according to a control program stored in the ROM 71.

  A motor 33 to be controlled and an ultraviolet irradiator 42 are connected to the control unit 7 via respective drive circuits. The obstacle sensor 35 and the imaging unit 44 described above are connected to the control unit 7, a remaining amount detector 73 for detecting the remaining charge amount of the rechargeable battery 6, and a transmission unit for transmitting to the external device. 74 are connected.

  The control unit 7 starts operation in response to an appropriate start operation, gives an operation command to the moving motor 33 and the ultraviolet irradiator 42, drives the moving motor 33, and operates the ultraviolet irradiator 42. The activation operation may be an operation of an activation switch (not shown) provided on the mobile unit 2 or an operation of an external device capable of communicating with the control unit 7.

  The moving body 2 is moved along the grip bar 10 by driving the moving motor 33, and the ultraviolet irradiator 42 irradiates the surface of the grip bar 10 with ultraviolet rays. The irradiation of the ultraviolet rays is performed continuously or intermittently in accordance with the movement of the mobile unit 2. The gripping bar 10 of the handrail 1 can be effectively disinfected without requiring any manual operation.

  During the above operation, the control unit 7 sequentially captures the output of the obstacle sensor 35, determines the presence or absence of an obstacle in front of the movement path, and when it is determined that there is an obstacle, the movement motor 33 and the ultraviolet irradiator 42. To perform a control operation to stop the moving motor 33 and the ultraviolet irradiator 42. The control unit 7 waits for the elapse of a preset standby time, and when the obstacle is no longer detected after the elapse of the standby time, releases the stop of the moving motor 33 and the ultraviolet irradiator 42. When the detection of the obstacle is continued, the control operation ends.

  The obstacle is, for example, a finger of a user holding the holding bar 10. In this case, since the mobile unit 2 is stopped by the above-described operation of the control unit 7, collision with the user can be avoided beforehand. Further, the operation of the ultraviolet irradiator 42 is also stopped, so that the influence of the ultraviolet light on the user can be eliminated. The standby time may be set to a time sufficient for the user to move (for example, several minutes). After the standby time elapses, the stop of the moving motor 33 and the ultraviolet irradiator 42 is released. Driving can be resumed automatically.

  The obstacle is, for example, a stopper provided at the end of the movement path. In this case, the mobile unit 2 and the ultraviolet irradiator 42 are stopped by the above-described operation of the control unit 7, and this state continues even after the elapse of the standby time. Therefore, the operation of the sterilization apparatus can be automatically stopped at the terminal position. it can.

  The control unit 7 also sequentially captures the output of the remaining amount detection unit 73 and monitors the remaining charge amount of the rechargeable battery 6. If the remaining charge amount falls below a predetermined value, the control unit 7 moves the mobile unit 2 to a point on the movement route. After moving to a predetermined stop position set in advance, a stop command is given to the moving motor 33 and the ultraviolet irradiator 42, and a control operation for stopping the moving motor 33 and the ultraviolet irradiator 42 is performed.

  The stop position is, for example, the position of a charging station provided in the middle of the movement route. In this case, the shortage of the remaining charge can be resolved by contact or non-contact charging with the charging station. In addition, the stop position is a position where collection by the user is easy. In this case, the shortage of the remaining charge amount can be resolved by charging by the collector. The control unit 7 operates according to the start operation again, and restarts the operation of the sterilization apparatus.

  The imaging unit 44 operates in response to an operation command from the control unit 7, and captures an image (moving image or still image) around the mobile body 2 as described above. The control unit 7 captures the captured image of the imaging unit 44 and transmits the captured image to an external device via the transmission unit 74. The user can visually recognize the captured image transmitted to the external device and appropriately grasp the situation around the moving position of the mobile unit 2. For example, when the operation of the sterilization apparatus is performed at night in a public facility such as a hospital or a nursing facility, the captured image can be effectively used as security information of the facility. Note that the imaging region of the imaging unit 44 is not limited to the above-described region, and for example, an omnidirectional camera capable of imaging in all directions may be used as the imaging unit 44. In addition, the captured image of the imaging unit 44 can be stored in a removable storage medium provided in the sterilization apparatus, and after the operation is completed, the storage medium can be taken out and the captured image can be reproduced to check the surrounding situation. is there.

  The transmitting unit 74 also has a function of transmitting the moving position of the mobile unit 2. The moving position can be transmitted, for example, as a GPS signal or a beacon signal. The user can check the moving position of the mobile unit 2 at any time from the peripheral information transmitted to the external device and monitor the operation status of the sterilization apparatus. For example, prompt recovery in the event of a failure or malfunction , Inspection becomes possible.

  Note that the transmitting unit 74 can also transmit an image around the mobile unit 2 and peripheral information other than the moving position of the mobile unit 2. For example, a human sensor that detects the presence or absence of a person in the vicinity of the mobile device 2 may be provided, and the detection result of the human sensor may be transmitted as peripheral information. The detection result of the human sensor can be used as nighttime security information, similarly to the captured image of the imaging unit 44. Further, the detection result of the human sensor can be used for the stop and restart control of the movement and the irradiation of the ultraviolet ray, similarly to the detection result of the obstacle sensor 35.

  The sterilization apparatus configured as described above can be provided as a handrail 1 that is provided in advance at an appropriate position of the continuous gripping rod 10. It is also possible to retrofit the existing handrail 1. The handrail 1 provided with the disinfection device is preferably provided with a coating of a photocatalytically active substance such as titanium dioxide on the surface of the gripping bar 10, that is, a so-called photocatalytic coating. The photocatalytic coating has an effect of enhancing the disinfection effect by ultraviolet irradiation.
